吡咯（Ｐｙ）在含有聚甲基丙烯酸甲酯（ＰＭＭＡ）的乙酸乙酯溶液中以三氯化铁（ＦｅＣｌ３）作为氧化剂进行原位化学氧化聚合，制备了可溶性的聚吡咯（ＰＰｙ）／ＰＭＭＡ导电复合材料。利用浇铸成膜的方法制得了导电复合薄膜材料，该薄膜（含Ｐｙ４０ｗｔ％）的电导率可达３２７Ｓ·ｍ－１（标准四电极法），并且在室温下的空气中有良好的稳定性。对影响聚合反应的诸因素（温度、时间、反应体系等）进行了探讨，确定了最佳的聚合反应条件。测试了复合材料的ＩＲ和ＧＰＣ谱。
Pyrrole (Py) was prepared by in situ chemical oxidative polymerization of FeCl3 in an ethyl acetate solution containing polymethylmethacrylate (PMMA) to prepare PPy / PMMA Composites. Conductive composite films were prepared by cast filming. The films contain Py40wt% conductivity of 327S · m-1 (standard four-electrode method), and have good stability in air at room temperature. The influencing factors of polymerization (temperature, time, reaction system, etc.) were discussed to determine the best polymerization conditions. The IR and GPC spectra of the composites were tested.
